If you’ve ever tried switching devices to play Honkai Star Rail, you know how frustrating it can be when you can’t remember your linked email or social media login off the top of your head. Many players don’t realize you don’t need those credentials to access your account, because you can use your unique player ID instead. We’ve tested every platform’s login flow to put together a no-nonsense walkthrough for how to log into Honkai Star Rail with UID, no extra hoops required. Whether you’re borrowing a friend’s PlayStation to run a few Simulated Universe runs, or switching from your PC to your phone while waiting for a bus, this guide will get you logged in in under two minutes.
Step-by-Step Instructions to Log Into Honkai Star Rail With UID
Before you start the login process, there are a few things you’ll need to have handy to avoid getting stuck mid-process. You don’t need any special tools, just basic information associated with your existing account:
- Your 9 or 10-digit Honkai Star Rail UID, which you can find on your profile screen if you’re still logged into your account on another device
- The password associated with your linked miHoYo/Hoyoverse account (you won’t need this if you have a linked phone number for one-time verification codes)
- Access to the email or phone number linked to your Hoyoverse account if you’re logging in from a new device that requires two-factor authentication
Once you have those items ready, the login process is almost identical across all supported platforms. First, open the Honkai Star Rail app on your device and wait for the initial loading screen to finish. When you reach the main login page, look for the “Log In with UID” option, which is usually placed below the more prominent social media and email login buttons. Tap or click that option to pull up the UID entry form.
Enter your full UID in the first field, then select your login method: either enter your Hoyoverse account password, or request a one-time verification code to be sent to your linked phone number or email. Enter the password or code in the second field, then tap the login button. If you’re logging in from a new device, you’ll get a prompt to enter a 2FA code sent to your linked contact method, which you’ll need to enter to confirm your identity.
Make sure you select the correct server associated with your UID before entering your credentials, because selecting the wrong server will throw an error even if your UID and password are correct. UID login is not available for guest accounts, so if you haven’t linked your guest account to a Hoyoverse account, you’ll need to do that first from your original logged-in device before you can use this login method.
Common Errors When Using UID Login for Honkai Star Rail (and How to Fix Them)
Even if you follow all the steps correctly, you might run into a few common errors that stop you from logging in. Most of these issues have simple fixes that take less than a minute to resolve, so you don’t have to panic if you see an error pop up.
The most common error is the “UID not found” message, which almost always happens when you select the wrong server for your account. Each Honkai Star Rail server has UIDs that start with a specific digit: North America UIDs start with 6, European UIDs start with 7, Asia Pacific UIDs start with 8, and Chinese server UIDs start with 1 through 5. You can identify your server by the first digit of your UID to avoid selection mistakes. If you’re sure you picked the right server, double check that you entered all digits of your UID correctly, because even one wrong digit will trigger this error.
Another common error is the “Invalid password or verification code” message. If you get this, first make sure you’re using the password for your Hoyoverse account, not the password for your linked Google, Facebook, or Twitter account. UID login only works with direct Hoyoverse account credentials, so social media passwords won’t work here. If you’re using a verification code, don’t wait more than 5 minutes to enter it, because these codes expire quickly, and you’ll need to request a new one if you miss the window.
If you get a “Too many login attempts” error, don’t keep trying to log in immediately, because that will extend the lockout period. Wait 15 minutes before trying again, or switch to a different verification method (like using a code sent to your email instead of your phone) to get around the lockout faster. Never share your verification code with anyone, even if they claim to be Hoyoverse support, as this will let them access your account.
Best Practices to Keep Your Account Secure When Using UID Login
UID login is incredibly convenient, but it’s important to follow a few basic security rules to make sure your account stays safe, especially if you’re logging in on devices that aren’t yours. These tips come from personal experience, so I can confirm they work to avoid unwanted account access.
First, always link your Hoyoverse account to both an active email address and a phone number, so you have backup verification methods if one stops working. I once lost access to the email I used to sign up for my account, and I only avoided losing years of progress because I had my phone number linked to request verification codes for UID login.
If you have to log into your account on a public or shared device, never save your password to the device, and always log out completely when you’re done playing. I learned this the hard way a few months ago, when I forgot to log out of my account on a friend’s laptop, and they accidentally spent 10 of my saved Star Rail Passes on a banner I didn’t want. It was an honest mistake, but it could have been much worse if they’d had bad intentions.
Turn on login notifications in your Hoyoverse account settings to get alerts every time someone accesses your account from a new device. This lets you spot unauthorized access immediately, so you can change your password and lock out anyone who shouldn’t be in your account before they can steal or delete anything. You should also change your Hoyoverse account password every 6 months to add an extra layer of security.
When You Can’t Use UID Login for Honkai Star Rail
UID login works for most scenarios, but there are a few cases where you won’t be able to use this method to access your account. It’s important to know these limits so you don’t waste time trying to use UID login when it won’t work.
First, UID login isn’t available for unlinked guest accounts, as we mentioned earlier. If you’ve been playing as a guest without linking your account to a Hoyoverse profile, you’ll only be able to access your account on the original device you used to create the guest profile. If that device breaks or you delete the app, you’ll lose all your progress permanently, so it’s always a good idea to link your account as soon as you start playing.
You also can’t use UID login to cross between regional versions of the game. If you downloaded the Chinese version of Honkai Star Rail, you can’t log into a global server UID, and vice versa. You’ll need to download the correct version of the game for your account’s region to use UID login. Some regions also have restrictions on UID login due to local data privacy laws, so if you don’t see the UID login option on your screen, you’ll have to use your linked social media or email login instead.
If your account has been suspended or banned for violating Hoyoverse’s terms of service, you won’t be able to log in with UID or any other method until you resolve the issue with support. You can submit an appeal through the Hoyoverse support website if you think the ban was a mistake, but you’ll need to provide proof of account ownership to get access back.
Logging into your account doesn't have to be a headache, especially when you have your UID handy. Whether you're switching devices temporarily or can't remember your linked email password, knowing how to log into Honkai Star Rail with UID saves you a ton of time that you could be spending pulling for your favorite 5-star character or clearing new story content. Just follow the steps we outlined, double check your server selection, and follow our security tips to keep your account safe every time you log in.
